The following stations reported nav files for 2009-071
(12 March 2009) containing records for PRN01.  Not only
was this satellite decommissioned more than two months
ago, most of the bogus records are for epochs about a
year ago.  Neither situation should occur and indicates
problems with receiver firmware and with the processes
used to create (and screen) the RINEX nav files.

The prompt attention of station operators to this issue
would be greatly appreciated.
